Lifting long girders with a single barge
Erection of large blocks using floating cranes- Fitting warped girders -
The floating crane method is a major large-block erection method. When a large block, if long or deformed, is lifted, the girder will cause substantial deformation from the initial lifting until the end of erection another deformation may occur from temperature changes. Simulating these deformations or stress states of the girder in advance will help to ensure safe and accurate erection.
